This mechanical aptitude cheat sheet boils the physics that mechanical comprehension tests actually measure down to a printable, at-a-glance rundown. It's a premium cheat sheet built by Capital Prep — the one premium prep we trust — and it's yours free. Reinforce it with the rest of your free mechanical aptitude toolkit: the practice test, study guide, and flashcards.
Mechanical Aptitude exam at a glance
- Type: A category of mechanical comprehension tests (Bennett/BMCT-II, Wiesen/WTMA, Ramsay, ASVAB) — not one single exam
- Questions: Typically about 30-60 multiple-choice (BMCT-II 55, WTMA 60)
- Time: Roughly 20-30 minutes (BMCT-II ~25 min, WTMA 30 min)
- Scoring: Raw score plus percentile rank; employers set their own cut score, often around 80%
- Published by: Pearson/TalentLens, Criteria Corp, Ramsay Corporation, and the U.S. military (ASVAB)
What’s on the Mechanical Aptitude cheat sheet
- Simple Machines (~40%) — the core: pulleys and mechanical advantage, the lever law, gear ratios, wheel-and-axle, the inclined plane, wedge, and screw.
- Forces & Motion (~25%) — inertia and Newton's first law, centripetal force and the tangent break, and resolving an angled force into components.
- Fluids & Pressure (~20%) — Pascal's principle, hydraulic force multiplication (force = pressure × area), pressure with depth, and buoyancy.
- Energy, Heat & Electricity (~15%) — gravity and falling, the three ways heat moves, series vs. parallel circuits, and center of gravity for stability.
How to use it in your final week
- Lock in the one rule behind every simple machine: mechanical advantage = output force ÷ input force, and a machine trades force for distance — it never gives free work.
- Give simple machines the most reps (about 40% of the questions). Drill pulley strands (fixed = 1, movable = 2), the lever law (effort × effort-arm = load × load-arm), gear ratios, and ramp advantage until they're automatic.
- Read the sheet the morning of the test for a final pass on the fast facts — Pascal's principle (force = pressure × area), tangent break on circular motion, series vs. parallel circuits, and low-plus-wide = most stable.
- Pair each review pass with a short timed practice set — you have roughly 25 to 30 seconds per question, so rehearse reasoning from a diagram at speed, not just recalling facts.

Mechanical Aptitude cheat sheet FAQ
Yes — the mechanical aptitude cheat sheet is 100% free to download as a PDF, with no sign-up required. It sits alongside Career Employer's free mechanical aptitude toolkit: the practice test, study guide, and flashcards.
The sheet condenses the highest-yield principles into a fast reference: the simple machines and their mechanical advantage, the lever law, gear ratios, Pascal's principle and hydraulics, force resolution, heat transfer, circuits, and center of gravity. It's grouped by the four topic areas every mechanical comprehension test draws from.
All of the common ones. Mechanical aptitude is a category, not one exam — the Bennett (BMCT-II, 55 questions in ~25 minutes), the Wiesen (WTMA, 60 questions in 30 minutes), the Ramsay tests, and the ASVAB Mechanical Comprehension subtest all rest on the same physics, so this cheat sheet preps you for whichever one your employer or the military uses.
There's no single national passing score — each version is scored as a raw count plus a percentile against a norm group, and every employer sets its own cut score, commonly around 80 percent correct. Because there's usually no penalty for wrong answers, you should answer every question even when guessing.
